To the Editor I read with interest the article “Association of Autism With Induced or Augmented Childbirth in North Carolina Birth Record (1990-1998) and Education Research (1997-2007) Databases” by Gregory et al1 after hearing about the study through the news media. The study is a retrospective observational study exploring the association of labor induction and/or augmentation with autism spectrum disorders. There are serious flaws in the methods, data source, and conclusions of this study.
